1		5.6	293	PROTEIN FROM THE PURPLE MEMBRANE WAS DELIPIDATED AND SOLUBILIZED IN OCTYL GLUCOSIDE. PROTEIN WAS CRYSTALLIZED FROM 60 - 70% (W/W) MONOOLEIN, 0.7 - 4.0 M NA/K - PHOSPHATE IN A PHOSPHATE BUFFER AT PH 5.6, AT 20C AND IN THE DARK. THE MIXTURE WAS CENTRIFUGED AT 10000G FOR 150 MN PRIOR TO CRYSTALLISATION.
